Disclosure Controls and Procedures; Deficiencies in or Changes to Internal Control Over Financial Reporting. The Company and the Subsidiaries (which, in the case of Patni, is to the Company’s knowledge, after due inquiry) have established and maintain disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)), which (i) are designed to ensure that material information relating to the Company and Patni, as applicable, including its consolidated subsidiaries, is made known to the Company’s or Patni’s, as applicable, principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company or Patni, as applicable, for effectiveness as of the end of the Company’s most recent fiscal quarter; and (iii) are effective in all material respects to perform the functions for which they were established. Based on the most recent evaluation of its disclosure controls and procedures, the Company is not aware of (i) any significant deficiencies or material weaknesses in the design or operation of

internal control over financial reporting which are reasonably likely to adversely affect the Company’s or Patni’s ability to record, process, summarize and report financial information or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s or Patni’s internal control over financial reporting. The statements relating to disclosure controls and procedures made by the principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Company in the certifications required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith are complete and correct.

Rating Agencies. No “nationally recognized statistical rating organization” (as such term is used under Section 15E of the Exchange Act) (i) has imposed (or has informed the

Company that it is considering imposing) any condition (financial or otherwise) to retain any rating assigned to the Company or any of the Subsidiaries or to any securities of the Company or any of the Subsidiaries or (ii) has indicated to the Company that it is considering (A) the downgrading, suspension, or withdrawal of, or any review (or of any potential or intended review) for a possible change in, any rating so assigned (including, without limitation, the placing of any of the foregoing ratings on credit watch with negative implications or under review for a possible change that does not indicate the direction of the possible change) or (B) any change in the outlook for any rating of the Company or any of the Subsidiaries or any securities of the Company or any of the Subsidiaries.

Guarantor. Other than the Guarantor, the Company has no wholly-owned domestic subsidiary which has Total Assets (as determined in accordance with generally accepted

accounting principles in the United States) and Consolidated EBITDA (each, as defined in the Indenture and measured, in the case of Total Assets, at the end of the most recent fiscal period for which internal financial statements are available and, in the case of Consolidated EBITDA, for the four quarters ended most recently for which internal financial statements are available, in each case measured on a pro forma basis after giving effect to any acquisitions or depositions of companies, division or lines of business since such balance sheet date or the start of such four quarter period, as applicable, and on or prior to the date of acquisition of such subsidiary) of 5.0% or more of the Company’s Total Assets and Consolidated EBITDA (the “Material Subsidiaries”). The subsidiaries which are not Material Subsidiaries do not collectively have Total Assets and Consolidated EBITDA of 5.0% or more of the Company’s Total Assets and Consolidated EBITDA.

This Agreement, Indenture, Registration Rights Agreement, Escrow Agreement and Escrow Account Security Deed. This Agreement has been duly and validly authorized, executed and delivered by the Company and the Guarantor. Each of the Indenture, the Registration Rights Agreement, the Escrow Agreement and the Escrow Account Security Deed has been duly and validly authorized by the Company and, if applicable, the Guarantor. Each of the Indenture, the Registration Rights Agreement, the Escrow Agreement and the Escrow Account Security Deed, when executed and delivered by the

Company and, if applicable, the Guarantor, will constitute a legal, valid and binding obligation of each of the Company and, if applicable, the Guarantor, enforceable against each of the Company and, if applicable, the Guarantor in accordance with its terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance, fraudulent transfer or other similar laws now or hereafter in effect relating to creditors’ rights generally, (ii) general principles of equity (whether applied by a court of law or equity) and the discretion of the court before which any proceeding therefor may be brought and (iii) with respect to the Registration Rights Agreement’s rights to indemnity or contribution thereunder, federal and state securities laws and public policy considerations. When executed and delivered, this Agreement, the Indenture, the Registration Rights Agreement, the Escrow Agreement and the Escrow Account Security Deed will conform in all material respects to the descriptions thereof in the Time of Sale Document and the Final Offering Memorandum. When executed and delivered by the Company and the Guarantor, the Indenture will meet the requirements for qualification under the Trust Indenture Act of 1939, as amended, and the rules and regulations of the SEC thereunder (collectively, the “TIA”).

No Conflicts. The Company’s, any Acquirer’s or Guarantor’s execution, delivery and performance of this Agreement, each Acquisition Agreement, Escrow Agreement, the Escrow Account Security Deed, the Indenture, the Registration Rights Agreement, the Credit Agreement, consummation of the transactions contemplated hereby and thereby and by the Time of Sale Document and the Final Offering Memorandum, including the issuance and sale of the Securities and the consummation of the Transactions (i) have been duly authorized by all necessary corporate action and will not result in any violation of the provisions of the charter or by-laws, partnership agreement or operating agreement or similar organizational document of the Company or any of the Subsidiaries, as

applicable, (ii) will not conflict with or constitute a breach of, or Default or a Debt Repayment Triggering Event (as hereinafter defined) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of the Subsidiaries (which, in the case of Patni, is to the knowledge of the Company, after due inquiry) pursuant to, or require the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any Applicable Law. As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of the Subsidiaries (which, in the case of Patni, is to the knowledge of the Company, after due inquiry).

Intellectual Property Rights. The Company and the Subsidiaries own or possess sufficient trademarks, trade names, patent rights, copyrights, domain names, licenses, approvals, trade secrets and other similar rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct their businesses as now conducted; and the

expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Effect. Neither the Company nor any of the Subsidiaries has received, or has any reason to believe that it will receive, any notice of infringement or conflict with asserted Intellectual Property Rights of others which could reasonably be expected to result in a Material Adverse Effect. The Company is not a party to or bound by any options, licenses or agreements with respect to the Intellectual Property Rights of any other person or entity that are required to be set forth in the Time of Sale Document and the Final Offering Memorandum and are not described therein. No claims or notices of any potential claim have been asserted by any person challenging the use of any such Intellectual Property by the Company or any of the Subsidiaries or questioning the validity or effectiveness of any Intellectual Property or any license or agreement related thereto, other than any claims that, if successful, would not, individually or in the aggregate, result in a Material Adverse Effect. To the Company’s knowledge, none of the technology employed by the Company or any of the Subsidiaries has been obtained or is being used by the Company or any of the Subsidiaries in violation of any contractual obligation binding on the Company or any of the Subsidiaries or any of its or the Subsidiaries’ officers, directors or employees or otherwise in violation of the rights of any persons.

Compliance with Environmental Laws. Except as would not, singly or in the aggregate, result in a Material Adverse Effect, (i) neither the Company nor any of the Subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment,

relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (ii) the Company and the Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of the Subsidiaries and (iv) there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of the Subsidiaries relating to Hazardous Materials or any Environmental Laws.

No Registration Required Under the Securities Act or Qualification Under the TIA. Without limiting any provision herein, no registration under the Securities Act and no qualification of the Indenture under the TIA is required for the offer or sale of the Securities to the Initial Purchasers as contemplated hereby or for the Exempt Resales, assuming (i) that the purchasers in the Exempt Resales are QIBs or are not “U.S. persons” (as defined under Regulation S of the Securities Act), (ii) the accuracy of each

(“OFAC”); and the Company will not directly or indirectly use the proceeds of the Offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

the use of the Time of Sale Document and the Final Offering Memorandum, and any amendments and supplements thereto prepared by, or approved in writing, by the Company, by the Initial Purchasers in connection with Exempt Resales).

Indemnification by the Company and the Guarantor. The Company and the Guarantor jointly and severally agree to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities of any kind to which

such Initial Purchaser, affiliate, director, officer, employee or such controlling person may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon:

Indemnification by the Initial Purchasers. Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless each of the Company, the Guarantor and their respective directors, officers, employees and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages, liabilities or expenses to which the Company, the Guarantor or any such director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as a court of competent jurisdiction shall have determined by a final, unappealable judgment

that such losses, claims, damages, liabilities or expenses (or actions in respect thereof) have resulted solely from (i) any untrue statement or alleged untrue statement of any material fact contained in the Time of Sale Document or the Final Offering Memorandum or any amendment or supplement thereto or (ii) the omission or the alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent (but only to the extent) that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Company by the Initial Purchasers specifically for use therein as set forth in Section 13; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any reasonable legal or other expenses incurred by the Company, the Guarantor or any such director, officer, employee or controlling person in connection with any such loss, claim, damage, liability, expense or action in respect thereof. The indemnity agreement set forth in this Section shall be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties.

Notifications and Other Indemnification Procedures. As promptly as reasonably practicable after receipt by an indemnified party under this Section of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve such indemnifying party from any liability under Section 8(a) or (b) above unless and only to the extent it is materially prejudiced as a proximate result thereof and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 8(a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may elect, jointly with any other indemnifying party similarly notified by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party, and the indemnified party shall have concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of

such indemnified party or parties at the expense of the indemnifying party. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of Section 8(a) or the Company in the case of Section 8(b), representing the indemnified parties under such Section 8(a) or (b), as the case may be, who are parties to such action or actions), (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section, in which case the indemnified party may effect such a settlement without such consent.

Settlements. No indemnifying party shall be liable under this Section for any settlement of any claim or action (or threatened claim or action) effected without its written consent, which shall not be unreasonably withheld, but if a claim or action settled with its written consent, or if there be a final judgment for the plaintiff with respect to any such claim or action, each indemnifying party jointly and severally agrees, subject to the exceptions and limitations set forth above, to indemnify and hold harmless each indemnified party from and against any and all losses, claims, damages or liabilities (and legal and other expenses as set forth above) incurred by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement or compromise of any pending or threatened proceeding in respect of which the indemnified party is or could have been a party, or indemnity could have been sought hereunder by the indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and substance satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of the indemnified party. Notwithstanding the foregoing, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for legal or other expenses as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement or compromise of, or

consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement or compromise of, or consent to the entry of such judgment.

Equitable Consideration. The Company, the Guarantor and each Initial Purchaser agree that it would not be equitable if the amount of such contribution determined pursuant to Section 8(e) were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in Section 8(e). Notwithstanding any other provision of this Section, no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchaser’s obligation to contribute hereunder shall be several in proportion to their respective purchase obligations hereunder and not joint. For purposes of Section 8(e), each director, officer and employee of any Initial Purchaser, and

each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as such Initial Purchaser, and each director, officer and employee of the Company and the Guarantor, and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and the Guarantor.

Beneficiaries. This Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Guarantor, the Initial Purchasers and to the extent provided in Section 8 hereof, the controlling persons, affiliates, officers, directors, partners, employees, representatives and agents referred to in Section 8 hereof and their respective heirs, executors, administrators, successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or

by virtue of this Agreement. The term “successors and assigns” shall not include a purchaser of any of the Securities from the Initial Purchasers merely because of such purchase. Notwithstanding the foregoing, it is expressly understood and agreed that each purchaser who purchases Securities from the Initial Purchasers is intended to be a beneficiary of the covenants of the Company and the Guarantor contained in the Registration Rights Agreement to the same extent as if the Securities were sold and those covenants were made directly to such purchaser by the Company and the Guarantor, and each such purchaser shall have the right to take action against the Company and the Guarantor to enforce, and obtain damages for any breach of, those covenants.
